STRAIN ER.

Specification of Letters Patent.

Patented Sept. 8, 1907.

Application filed June 8,1907. Serial No. 377.992.

To all whom it may concern.'

Be it known that I, WILLARD JONES, a citizen of the United States, residing at Auburn, in the county oi Androscoggin and State ol' Maine, have invented a 1" ,w and uselul Strainer, oi which the following is a spe iication.

This invention relates to strainers ior milk pails.

The object ol the invention is to provide a simple and thoroughly ef'licient form oi strainer which shall be 'capable of assemblage with a pail and in which the passage of loi-eign or extraneous matter of any kind to the pail will be positively prevented, and whereby further the thorough straining of the milk will be secured. Furthermore, to provide a strainer in which the parts shall be capable of ready disconnection for purposes oi cleansing, whereby thorough sanitation may at all times be maintained.

W ith the above and other objects in view, as will appear as the nature oi the invention is better understood, the same consists in the novel construction and combination oi parts of a strainer, as will be hereinafter' fully described and claimed.

In the accompanying drawings forming a part`oi this specification and in which like characters oi `reference indicate corresponding parts,Figu1-e l is a view in vertical longitudinal section through a strainer constructed in accordance with the present invention. Fig. 2 is a horizontal plan view taken on the line 2 2 oi Fig. l. Fig. 3 is a collective detail perspective view oi a portion oi the strainer, the parts being separated and arranged in the order in which they are assembled in use.

lelerri ng to the drawings, l designates the receiver or body oi the strainer which is herein shown as an inverted truncated structure, and to which is attached a flange 2 that is adapted to fit within a milk or other pail, the flange being provided with a marginal bead 3 to limit its insertion within the bucket or pail.

The bottom 4 of the body is provided with a tubular extension 5 that is circumierentially reduced adjacent to the bottom, to provide a seat 6 to receive a pair of strainers 7 and 8, of which the latter is of relatively coarse mesh and maybe constructed either of foraminous or reticulated metal, and the former oi fine mesh. and constructed preierably of reticulated metal. In order to hold the two strainers 7 and 8 in position the bottom 4 is provided with two inward projecting studs or bosses 9 that, as clearly shown in Fig. 2, project over the strainer 8, which latter is provided in its periphery with a notch l0 to permit it to be positioned relatively to the bottom.

The strainer 7 being of line mesh may readily be flexed to place it within the seat, but the strainer 8 being relatively stiii it is oi advantage to provide the notch l0 referred to for the purpose. When the strainers 7 and 8 are in position, by turning the strainer 8 -a short distance to remove the notch from beneath one of the lugs 9, both strainers will be held in position against accidental separation, but may readily be removed fer purposes oi cleansing.

Combined with the extension 5 is a supplemental strainer, which comprises a cup ll constituting a trap and having a collar llEL adapted to fit upon the extension 5 and be held in position by irictional contact therewith. The bottom l2 of the cup is preferably dished, and is provided with a double reduced eXtension 13, the purpose of which will presently appear. The other elements oi the second or supplemental strainer comprise a head 14, a pair of annular strainers l5 and 16, ol which the ici-mer is of fine mesh and the latter oi relatively coarse mesh, a thimble 17 provided with a flange 17L and an approximately hemispherical cap or deflector 18. The head lli has an openwork or gridded top 19, from the center of which projects a sleeve 20 that is of the same diameter as the small portion 2l of the extension 13 and is designed to abut thereagainst when the parts of the two strainers are assembled, as clearly shown in Fig. l. The head, as clearly shown in Fig. l, is oi less cross diameter than the tubular extension 5, whereby there is lelt a circular passageway 2l for the escape oi milk from the receiver to the trap. The annular strainer-s l5 and I6 are designed to fit snugly within the head and are held in position therein by the liange of the cap I8. The thimble is of a diameter to lit snugly within the sleeve 20 and the extension 2l oi the cup, thereby to hold the head and strainers assembled with the latter, and the cap 18 engages irictionally with the interior of the head 14 and is thus held for ready disconnection therefrom.

It will be seen that by the manner of assembling the parts of the supplemental strainer, separation thereof for 'the purpose oi cleansing may readily be effected so that the article may at all times be kept in a clean and sanitary condition.

In the use ofthe utensil, the body is positioned upon the pail. As the milk is supplied to the body it passes down through the strainers 8 and 7, and onto cap 18 by which it is deiiected towards the passageway 2l through which it passes to the cap 11, thence upwards through the openings 22 in the head I4v and through the strainers l5 and 16, and thence downward through the thimble into the pail. It will thus be seen that initially any extraneous matter, such as dirt or hairs, will be eiiectually separated from the milk by the strainers 7 and 8, and that by subjecting it to a second straining through the strainers l5 and 16, any foreign matter that may have passed through the lirstenamed strainers will be caught and retained in the cup ll, whence it may be removed by separating the parts in the manner described.

What is claimed is:-

l. A strainer element comprising a cup, an openwork head, annular strainers disposed within the head, a thmble for holding the strainers, head and collar frictionally assembled, and a cap detachably combined with the head.

2. A strainer element comprising a cup having a reduced extension, an openwork head having a sleeve, annular strainers arranged within the head, a thimble projecting through the extension and into the sleeve and having a Ilange bearing against the extension, and a substantially hemispherical cap carried by the head.

Il. A strainer comprising a receiver provided with means i'or attachment to a pail, primary straining elements detachably combined with the receiver, and a supplemental strainer assembled with the receiver and embodying a trap, secondary straining elements arranged therein, and a cap assembled with the trap.

Ll. A strainer comprising a receiver, primary strainers arranged therein, a trap carried by the receiver, secondary sti-:liners in the trap, and a deflector arranged over the last named strainers and under the first named.

Beads? 5. A strainer comprising a receiver, primary strainers therein, a trap carried by the receiver, a head disposed within the trap and provided with openings, secondary strainers arranged over the openings, and a deiector carried by the head and covering the last-named strainers and openings.

G. A strainer comprising a receiver having a tubular extension provided with a seat, primary strainer-s disposed in the seat, a trap engaging the extension, a head arranged Within the trap and provided with openings, strainers can ried by the head and covering the openings thereof, a thimble for holding the head assembled with the trap, and a dellector carried by the head and covering the secondary strainer-s.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
